"I wanted to find out what it was I wanted to say, what story I wanted to tell. The project grew out of a wish to peel away effects and see what was hiding underneath them. In more concrete terms, I made rules about paper type, size, and exactly what kind of pen I could use. I had to see what could come out of it – how far I could stretch the idea, working without any kind of technical devices, huge screens or tons of cool colours at my disposal. I wanted to backtrack to pure content."
